I'm Too Easily Diverted

Ever on the lookout for more excuses on-line for procrastination under the guise of keeping the grey cells in tiptop form, I happened upon this simple, but maddening word game.

The object is to determine the appropriate five-letter word (I'm really practiced at the four-letter ones). Each time you guess, you will be shown whether your word was before or after the goal word alphabetically. Simple, eh? How many five-letter words are there anyways? Actually, a whole shitload when you consider that most four-letter words can be extended by an -s or -d or -y.

My best score is 10,893. What's yours?

And don't forget your blends, dipthongs and digraphs.
